Naulin Xo Fine Cognac (kosher for Passover)NAULIN COGNAC is a very old brand of blended eaux de vie that expresses the regions various Crus. Offering a balance between tradition and modern appeal, NAULIN gains its generosity, simplicity and aromatic profile from the meticulous work of the Boinaud Family, who distil, age and blend the spirit that you now hold in your hands. It is thanks to this dedication and integrity that the Boinauds today own the largest family operated winery in Cognac.
